A display apparatus includes a back-light unit including a second light-guide plate disposed on a first light-guide plate and a light-source element; a liquid crystal panel on the second light-guide plate of the back-light unit; a first viewing angle control unit disposed between the first light-guide plate and the second light-guide plate of the back-light unit, the first viewing angle control unit including first light-blocking patterns; and a supporting element disposed between an edge of the first light-guide plate and an edge of the first viewing angle control unit, wherein the light-source element includes a first light-source on a side of the first light-guide plate, a second light-source on a side of the second light-guide plate, and a light-source circuit board in which the first light-source and the second light-source are mounted, and wherein the supporting element is in contact with a surface of the light-source circuit board between the first light-source and the second light-source, thereby preventing deterioration of an image quality due to particles generated during a coupling process of the supporting element.
